Structure and Working Principle
Structure: Composed of valve body, valve stem, valve core, valve seat, packing, and gland. The needle-shaped valve core achieves precise sealing with the seat.
Principle: Rotating the valve stem moves the valve core up and down, precisely adjusting the gap to control or cut off medium flow.
Key Advantages
- Good Sealing Performance: Small contact area between core and seat ensures high sealing pressure, preventing leakage even under extreme high pressure.
- Strong Pressure Resistance: High-strength stainless steel construction withstands pressures from 1.6MPa up to 32.0MPa.
- Accurate Flow Control: The fine needle structure allows for precise adjustment of small flow rates.
- Long Service Life: Excellent corrosion and wear resistance. Only vulnerable parts need replacement if the sealing surface is damaged.
